Supported Features

.. zephyr:board-supported-hw::

System Clock

The MGM260P Module is configured to use the HFRCODPLL oscillator at 80 MHz as the system clock, locked to the 40 MHz crystal oscillator.

Serial Port

The MGM260P Module has 3 USARTs and 4 EUSARTs. USART0 is connected to the board controller and is used for the console.

Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

Connect the board to your host computer using the USB port.

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mgm260p_rb4350a :goals: flash

Open a serial terminal (minicom, putty, etc.) with the following settings:

Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1

Reset the board and you should see the following message in the terminal:

.. code-block:: console

Hello World! mgm260p_rb4350a

Bluetooth

To use Bluetooth functionality, run the command below to retrieve necessary binary blobs from the Silicon Labs HAL repository.

.. code-block:: console

west blobs fetch hal_silabs

Then build the Zephyr kernel and a Bluetooth sample with the following command. The :zephyr:code-sample:bluetooth_observer sample application is used in this example.

.. zephyr-app-commands:: :zephyr-app: samples/bluetooth/observer :board: mgm260p_rb4350a :goals: build
